Arduino RC Car help

Hello fourm!

I want to wire into a rc receiver board I found that has a SM6130 (B) chip on it. I can't find a pin out and the motor wires have fallen off. Can anyone help me find the pin out and the wire's position.

Thanks!
PS. No power is required for the circuit (via the chip).
